[0028]
[0029] The term "detection area" includes the concept of a partial area of the variable cooking surface area in which the control unit performs the detection of the supported cooking battery in at least one operating state and / or searches for the battery of cooking supported.
[0030]
[0031] The term "already existing" heating zone configuration in the variable cooking surface area includes the concept of a heating zone configuration that is present and, advantageously, heated, in the variable cooking surface area when placed the new cooking battery supported and / or which is configured and / or formed in time before the new cooking battery is installed.

[0036]
[0037] The term "cooking battery configuration" includes the concept of a property that characterizes the cooking battery arranged on the cooking field to be heated by it. The cooking battery configuration could be, for example, the arrangement of cooking batteries in the variable cooking surface area in an absolute and / or relative manner with respect to at least one defining edge of the variable cooking surface area and / or relative to at least one edge of the cooking field and / or relative to each other.

[0038]
[0039] As an example, in the case of a first heating zone configuration, the control unit selects a first detection mode from the set of detection modes in the operating state. Also by way of example, in the case of a second different heating zone configuration with respect to the first heating zone configuration, the control unit selects a second detection mode in the operating state, different from the first detection mode, from the set of detection modes.

[0041] The term “planned” includes the concept of programmed, conceived and / or provided in a specific way. The expression that an object is intended for a function determined includes the concept that the object satisfies and / or performs this function determined in one or more application and / or operating states.
[0042]
[0043] Likewise, it is proposed that the control unit be provided to avoid and / or minimize intermodulation hums in the operating state by selecting at least one appropriate detection mode from the set of detection modes to perform a detection in at least A detection area. To carry out a detection in the detection area, the control unit selects in at least one operating state at least one detection mode of the set of detection modes whereby intermodulation hums are minimized according to the calculations made by the unit of control and / or the information stored in the storage unit. In this way, the supported cooking battery can be detected silently, thus achieving great comfort of use and / or thus avoiding the impression that the cooking field is defective, which could be caused by the appearance of buzzing sounds. intermodulation
[0044]
[0045] In the event that it is ruled out and / or impossible to avoid intermodulation buzzing and detection in the detection area simultaneously, the control unit could, for example, prioritize at least one state of operation. detection in the detection area and detect the cooking battery supported in the detection area producing intermodulation hum. Preferably, in the event that it is ruled out and / or impossible to avoid intermodulation buzzing and detection in the detection area simultaneously, the control unit is provided in the operating state to prioritize the avoidance of intermodulation humming and not detecting in the detection area.
[0046]
[0047] In the event that it is ruled out and / or impossible to avoid intermodulation buzzing and detection in the detection area simultaneously, the control unit prioritizes in at least one operating state the avoidance of buzzing sounds. intermodulation with respect to detection in the detection area. By way of example, in at least one operating state, the control unit could issue to the user through the user interface information regarding the detection in the detection area being postponed and / or discarded, and / or one or more control requirements for the firing battery to rest on another detection area. The other detection area could be arranged spaced from the detection area in which the detection is postponed and / or discarded. Thus, great comfort of use can be achieved.
[0048] By way of example, the variable cooking surface area could have at least a first partial cooking surface area and at least a second partial cooking surface area. In at least one operating state, the first heating units that define the first partial cooking surface area and the second heating units defining the second partial cooking surface area could be connected, for example, to a phase of The common grid current voltage. Advantageously, the first heating units defining the first partial cooking surface area and the second heating units defining the second partial cooking surface area are connected to different grid current voltage phases in the less a state of operation. Preferably, the variable cooking surface area has at least a first fixedly defined first cooking surface area, which is defined by first heating units of the heating units that in the operating state are connected to a first phase of the mains current voltage, and at least a second fixedly defined partial cooking surface area, which is defined by second heating units of the heating units that in the operating state are connected to a second phase of the mains current voltage, different from the first phase of the mains current voltage. At least a part of the heating units define the first partial cooking surface area and are referred to below as the first heating units. In at least one operating state, the first heating units are connected to the first phase of the mains current voltage. At least a part of the heating units define the second partial cooking surface area and are referred to below as second heating units. In at least one operating state, the second heating units are connected to the second phase of the mains current voltage. The term "fixed area" partial cooking surface area includes the concept of a partial cooking surface area whose position is fixed and / or predetermined in a non-modifiable manner and / or regardless of the heating zone configuration and / or the cooking battery configuration for at least one property, for example, for at least one structural and / or electrical and / or spatial property, and / or for at least one marking, in any operating state. By way of example, a fixedly defined partial cooking surface area could be fixed in a non-modifiable and / or constant manner by at least connecting the heating units defining the partial cooking surface area to a phase of the common network current voltage and / or by the spatial arrangement of the heating units that define the partial area of cooking surface The term "phase of the network current voltage" includes the concept of a phase of a home network, specifically, exactly one phase of a home network. The first phase of the network current voltage and the second phase of the mains current voltage could be offset with a phase angle of approximately or exactly 120 °. Thus, a high total output power can be provided, so that it is possible to heat at the same time a large number of batteries of cooking and, with this, a great comfort of use is possible.
[0049]
[0050] In addition, it is proposed that, in at least one of the detection modes, the control unit detects in the operating state the new cooking battery supported in at least one of the partial cooking surface areas exclusively without grid voltage. of one of the phases of the mains current voltage. The expression "without grid voltage" includes the concept that at least one of the, preferably, at least a large part of the heating units is not applied grid voltage of at least one domestic network and , advantageously, that none of the heating units have mains voltage from at least one home network applied in. In at least one operating state, the mains voltage of at least one home network is prevented from reaching the at least one of the, preferably, at least a large part of the and, advantageously, none of the heating units, by way of example, the control unit could deactivate the heating units and / or separate them from the mains voltage and then detect the new cooking battery supported.Alternatively or additionally, the control unit could detect at least one operating state the new cooking battery supported at an interval close to a zero crossing of the grid voltage. Thus, it is possible to avoid intermodulation buzzes in a particularly effective and / or safe manner, which allows great convenience of use.
[0051]
[0052] Likewise, it is proposed that, for the selection of the detection mode, the control unit divides in the operating state at least one of the partial cooking surface areas in at least two and, advantageously, in at least three sections of cooking surface defined in a fixed way and select for at least one of the cooking surface sections at least one detection mode of the set of detection modes depending on the overlapping of an area close to at least one heating zone of the configuration of heating zone and cooking surface section. In at least one operating state, the control unit divides the first partial cooking surface area into at least two and, advantageously, into at least three fixedly defined cooking surface sections and divides the second partial area of cooking surface in at least two and, advantageously, in at least three sections of cooking surface defined in a fixed way. In at least one operating state, the control unit divides the first partial cooking surface area and the second partial cooking surface area in the same way and / or analogously with respect to each other. In this way, for each of the cooking surface sections, an appropriate detection mode can be flexibly selected from the set of detection modes, whereby the supported cooking battery can be optimally detected and / or avoiding the intermodulation hums.
[0053]
[0054] In addition, it is proposed that the control unit divides in the operating state the cooking surface sections of at least one of the partial cooking surface areas depending on the electrical and / or magnetic coupling of the heating units defining the heating corresponding cooking surface section with at least one heating unit that partially or completely defines another of the partial cooking surface areas. The expression that a heating unit defines "partially or completely" a partial cooking surface area includes the concept that the heating unit defines the partial cooking surface area alone or together with at least one other cooking unit. heating. In at least one operating state, the control unit could divide the partial cooking surface area into at least two and, advantageously, into at least three cooking surface sections. Advantageously, the control unit divides the partial cooking surface area in the operating state into at least a relatively intense coupling cooking surface section and / or at least a relatively moderate coupling cooking surface section and / or at least one section of relatively weak coupling cooking surface. The term "relatively" intense or moderate or weak coupling includes the concept of a coupling that is intense or moderate or weak compared to and / or in relation to the maximum possible coupling and / or the coupling that occurs at most in less a state of operation. By way of example, the relatively intense coupling could adopt a value of at least 50%, preferably, at least 60%, advantageously, at least 70% and, preferably, at least 80% of the maximum possible coupling and / or the coupling that occurs at most in at least one operating state. Also by way of example, the relatively weak coupling could adopt a maximum value of 30%, preferably, a maximum of 20%, advantageously, a maximum of 15% and, preferably, a maximum of 10% of the maximum possible coupling and / or the coupling that occurs at most in at least one operating state. Also as an example, the coupling relatively moderate could adopt a value that could be found between the relatively strong coupling value and the relatively weak coupling value. Thus, different couplings can be taken into account, which makes it possible to avoid and / or minimize intermodulation hums specifically.
[0055]
[0056] Likewise, it is proposed that, in the case of a detection area that overlaps with at least one relatively moderate or relatively intense coupling cooking surface section of the cooking surface sections and that is arranged in an area close to minus one heating zone of the heating zone configuration, the control unit deactivates one or more of the operating conditions and, in particular, all of the heating units that heat the heating zone for detection. One of the detection modes of the set of detection modes is called "relatively intense coupling detection mode" and comprises that, in the case of a detection area that overlaps with at least one section of the coupling coupling cooking surface relatively intense of the cooking surface sections and that is arranged in an area close to at least one heating zone of the heating zone configuration, the control unit deactivates one or more of the units and, in particular, all of the units of heating that heat the heating zone to perform the detection One of the detection modes of the set of detection modes is called "relatively moderate coupling detection mode" and comprises that, in the case of a detection area that is overlap with at least one relatively moderate coupling cooking surface section of the cooking surface sections and which is placed in an area close to at least one heating zone of the heating zone configuration, the control unit deactivates one or more of the and, in particular, all of the heating units that heat the heating zone to effect the detection. Thus, it is possible to prevent the coupling between heating units that heat the heating zone and heating units that are arranged in the detection area, so that the appearance of intermodulation hums can be prevented and / or ruled out.
[0057]
[0058] Furthermore, it is proposed that, in the case of a detection area that overlaps with at least one relatively weak or relatively moderate coupling cooking surface section of the cooking surface sections and that is arranged in an area close to the minus one heating zone of the heating zone configuration, the control unit selects in the operating state a detection mode from the set of detection modes in which a detection carried out by the at least one heating unit that partially or completely defines one of the partial cooking surface areas is synchronized with at least one other heating unit that partially or completely defines the partial cooking surface area if the heating zone is arranged at less partially in the first partial cooking surface area and in the second partial cooking surface area, and which is called "detection mode within the partial cooking surface areas." In at least one operating state, the control unit selects the detection mode within the partial cooking surface areas of the detection mode set, in the case of a detection area that overlaps with at least one relatively weak coupling cooking surface section or relatively moderate of the cooking surface sections of one of the partial cooking surface areas If, in particular, some heating zones of the heating zone configuration are at least partially arranged in the first partial cooking surface area and in the second partial cooking surface area. The expression that a heating zone is arranged "at least partially" in a partial cooking surface area includes the concept that at least a partial area of the heating area is arranged in the partial cooking surface area since at least one heating unit that partially or completely defines the partial cooking surface area heats the heating zone in the operating state. In the detection mode called "detection mode within the partial surface areas of cooking ”, by way of example a detection made by at least one first heating unit is synchronized with at least another first heating unit if the heating zone is at least partially arranged in the first partial cooking surface area and in the second partial cooking surface area. Alternatively or additionally, in the detection mode called "detection mode within the partial cooking surface areas", by way of example a detection carried out by at least one second heating unit is synchronized with at least another second unit heating if the heating zone is at least partially arranged in the first partial cooking surface area and in the second partial cooking surface area. In the operating state, the control unit selects the detection mode called "mode of detection within the partial cooking surface areas ”for one of the partial cooking surface areas if it is ruled out that there are couplings and / or interferences of at least one heating unit that partially or completely defines the partial area of cooking surface with at least one heating unit that partially or completely defines ot ra of the partial cooking surface areas.
[0059] Thus, it is possible to avoid interference and / or couplings between first heating units and second heating units, thus making it possible to detect the cooking coil silently and / or with little noise.
[0060]
[0061] As an example, for the detection of the cooking battery, the control unit could select in at least one operating state exclusively the relatively intense coupling detection mode and / or the relatively moderate coupling detection mode and / or the detection mode within the partial cooking surface areas of the set of detection modes. Preferably, in the case of a detection area that is arranged in the second partial cooking surface area, the control unit selects in the operating state a detection mode from the set of detection modes called "mode of detection between the partial cooking surface areas ”and in which a detection carried out by at least a second heating unit is synchronized with at least a first heating unit of the first heating units if the second partial surface area of cooking does not have heating zones of the heating zone configuration In the case of a detection area that is arranged in the first partial cooking surface area, the control unit selects a detection mode in the operating state set of detection modes called "detection mode between partial areas of cooking surface and in which a detection made by at least a first heating unit is synchronized with at least a second heating unit of the second heating units if the first partial cooking surface area does not have heating zones of the zone configuration of heating. In this way, it is possible to detect the cooking battery supported with precision and / or accuracy and / or without disturbances.
[0062] In at least one operating state, the control unit could detect a new cooking battery supported on the variable cooking surface area continuously and / or regardless of the degree of coverage of at least one heating unit and / or regardless of your placement position. Preferably, the control unit detects in the operating state a new firing battery supported in the variable cooking surface area, in particular, in the relatively intense coupling cooking surface section and / or in the cooking section. relatively moderate coupling cooking surface, which is supported on at least two heating units arranged directly adjacent to each other whose central points are arranged on a straight line that is oriented approximately or exactly perpendicular to at least one edge of cooking field, only in the case that at least one of the at least two heating units is covered at least 50%, preferably at least 60%, advantageously, at least 65%, particularly advantageously , at least 70%, preferably, at least 75% and, particularly preferably, at least 80%. In order to detect the supported cooking battery, the control unit assumes in at least one operating state that the cooking battery is an appropriate cooking battery optimally in terms of its material and / or shape and / or size. In the case of an appropriate cooking battery optimally and that the cooking battery covers one or more heating units in approximately or exactly 100%, the coupling between the cooking battery and the heating unit of the heating units Heating covered by the cooking battery is optimal and adopts a certain optimum value. If the cooking battery covers the heating unit to a lesser extent, the coupling adopts a value that is less than the determined optimum value. In the case of an improper cooking battery and if the cooking battery covers one or more heating units at approximately or exactly 100%, the coupling adopts a value that is less than the determined optimum value. In at least one operating state, the control unit assumes for the detection of the supported cooking battery that this is an optimally suitable cooking battery. If the cooking battery is not appropriate, the control unit detects in a working state at least a degree of coverage that is actually lower than the existing one, as in the case that the cooking battery is optimally appropriate, and treats the Inappropriate cooking battery of larger size as an appropriate cooking battery of optimum size and smaller size. The expression "approximately or exactly perpendicular" includes the concept of the orientation of a direction relative to a reference direction, where, observed in a plane, the direction and the reference direction enclose an angle of 90 ° and the present angle a maximum deviation of 8 ° maximum, advantageously, 5 ° maximum and, particularly advantageously, 2 ° maximum. The term "cooking field edge" includes the concept of a lateral delimitation of the plate of support when observed perpendicularly on the main extension plane of the support plate. Thus, to heat the cooking battery, it is possible to ensure that the cooking battery sufficiently covers one or more heating units, so that optimum cooking results can be achieved. In particular, heating of inappropriate cooking batteries can be ruled out.
[0063]
[0064] As an example, the control unit could detect in at least one operating state a new firing battery supported by the variable surface area of cooking, which is supported on at least two heating units arranged directly adjacent to each other whose central points are arranged on a straight line that is oriented approximately or exactly perpendicular to at least one edge of cooking field, only in the case that at least one of the at least two heating units is covered at least 50%, preferably at least 60%, advantageously, at least 65%, particularly advantageously, at least 70%, preferably at least 75% and, particularly preferably, at least 80%. Preferably, the control unit detects in the operating state a new firing battery supported in the variable cooking surface area, in particular, in the relatively intense coupling cooking surface section and / or in the cooking section. relatively moderate coupling cooking surface, which is supported on at least two heating units arranged directly adjacent to each other whose center points are arranged on a straight line that is obliquely oriented with respect to at least one cooking field edge, only in the case that at least one of the at least two heating units is covered at least 10%, preferably at least 15%, advantageously, at least 20%, so particularly advantageous, at least 25%, preferably, at least 27% and, particularly preferably, at least 30%. The term "obliquely oriented" with respect to at least one cooking field edge includes the concept of a straight line that encloses with the cooking field edge a minimum angle of 85 ° maximum, preferably 80 ° as maximum, advantageously, maximum 75 °, particularly advantageously, maximum 70 °, preferably 65 ° maximum and, particularly preferably, 60 ° maximum, and 5 ° as minimum, preferably, at least 10 °, advantageously, at least 15 °, particularly advantageously, at least 20 °, preferably, at least 25 ° and, particularly preferably, of 30 ° minimum. In this way, it is possible to detect and / or heat even cooking batteries that partially or completely cover two or more heating units arranged adjacent to each other obliquely, which makes it possible to achieve great comfort of use.
[0065]
[0066] Likewise, an optimized detection of the cooking battery can be achieved by means of a cooking field, in particular, by an induction cooking field, with at least one cooking field device according to the invention.
[0067] The cooking battery detection can be further optimized by a procedure for the operation of a cooking field device with multiple heating units defining at least one variable cooking surface area, where, for the detection of at least one new cooking battery supported in the variable cooking surface area, in at least one operating state at least one detection mode is selected from a set of possible detection modes depending on a heating zone configuration already existing in the variable area of cooking surface.

[0090]
[0091] Figure 1 shows a cooking field 40a, which is made as an induction cooking field and which has a cooking field device 10a, which is made as an induction cooking device.
[0092]
[0093] The cooking field device 10a has a support plate 42a. In this exemplary embodiment, the support plate 42a is made as a cooking field plate. In the assembled state, the support plate 42a forms a part of the outer housing of the cooking field 40a. The support plate 42a is provided to support the cooking battery 60a (see figures 2 to 13).
[0094]
[0095] The cooking field device 10a has multiple heating units 12a for heating the cooking battery 60a. Only one of each of the objects present several times is accompanied by a reference symbol in the figures. In this exemplary embodiment, the cooking field device 10a has fifty-six heating units 12a. In the installation position, the heating units 12a are arranged under the support plate 42a. The heating units 12a are provided to heat the cooking battery 60a placed on the support plate 42a above the heating units 12a. In this exemplary embodiment, the heating units 12a are made as induction heating units.
[0096]
[0097] In addition, the cooking field device 10a has a user interface 44a for the introduction and / or selection of operating parameters, for example, the heating power and / or the density of the heating power and / or the area of heating 28a. Also, the user interface 44a is intended to give the user the value of an operating parameter.
[0098]
[0099] The cooking field device 10a also has a control unit 38a. The control unit 38a is intended to execute actions and / or modify settings depending on the operating parameters entered through the user interface. user 44a. In a heating operating state, the control unit 38a regulates the power supply to the heating units 12a.
[0100]
[0101] The heating units 12a define a variable cooking surface area 14a. The variable cooking surface area 14a has a first partial cooking surface area 16a and a second partial cooking surface area 18a. The first partial cooking surface area 16a and the second partial cooking surface area 18a are arranged adjacent to each other and partially adjoin one another. In this exemplary embodiment, the first partial cooking surface area 16a and the second partial cooking surface area 18a are arranged in an operating state adjacent to each other in the transverse direction 46a.
[0102]
[0103] The first heating units 12a1 of the heating units 12a define the first partial cooking surface area 16a. The first partial cooking surface area 16a is defined by first heating units 12a1. The amount of first heating units 12a1 amounts to 50% of the total number of heating units 12a. The first heating units 12a1 of the heating units 12a defining the first partial cooking surface area 16a are connected in an operating state to a first phase of the mains current voltage 48a.
[0104]
[0105] The second heating units 12a2 of the heating units 12a define the second partial cooking surface area 18a. The second partial cooking surface area 18a is defined by second heating units 12a2. The amount of second heating units 12a2 amounts to 50% of the total number of heating units 12a. The second heating units 12a2 of the heating units 12a defining the second partial cooking surface area 18a are connected in an operating state to a second phase of the mains current voltage 50a, other than the first phase of the mains current voltage 48a.
[0106]
[0107] For the detection of at least one new cooking battery 60a supported on the variable cooking surface area 14a, the control unit 38a selects in a state of operation a detection mode of a set of possible detection modes depending on a heating zone configuration already existing in the variable cooking surface area 14a. For each new cooking battery 60a supported in the variable cooking surface area 14a, the control unit 38a selects in a working state a detection mode from the set of possible detection modes in dependence on an existing heating zone configuration in the variable cooking surface area 14a.
[0108]
[0109] In an operating state, the control unit 38a selects for a given cooking battery 60a that detection mode from the set of possible detection modes with which the intermodulation hums are avoidable and / or minimizable. For detection in the detection area 30a, the control unit 38a prevents intermodulation hums in the operating state by selecting at least one appropriate detection mode from the set of detection modes.
[0110]
[0111] In the event that it is ruled out that the avoidance of intermodulation hums and the detection in the detection area 30a take place simultaneously, the control unit 38a prioritizes in the operating state the avoidance of intermodulation hums. In the event that it is ruled out that the avoidance of intermodulation hums and detection in the detection area 30a take place simultaneously, the control unit 38a omits in the operating state the detection in the detection area 30a in favor of the avoidance of intermodulation hums.
[0112]
[0113] In the operating state, the control unit 38a detects the cooking battery 60a supported exclusively without there being mains voltage of at least one of the phases of the mains current voltage 48a, 50a. In each of the detection modes, the control unit 38a detects in the operating state in at least one of the partial cooking surface areas 16a, 18a the new cooking battery 60a supported without having mains voltage of one of the phases of the mains current voltage 48a, 50a.
[0114]
[0115] For the selection of the detection mode, the control unit 38a divides in the operating state each of the partial cooking surface areas 16a, 18a into three cooking surface sections 20a, 22a, 24a. In the operating state, the control unit 38a divides each of the partial cooking surface areas 16a, 18a into a relatively weak coupling cooking surface section 20a, a relatively moderate coupling cooking surface section 22a, and a cooking surface section 24a of relatively intense engagement.
[0116]
[0117] When viewed perpendicularly on the main extension plane of the support plate 42a, the cooking surface section 24a of relatively intense engagement is arranged in a corresponding area of the partial cooking surface area 16a, 18a that borders the other of the partial cooking surface areas 16a, 18a in the transverse direction 46a. When observed perpendicularly on the plane of main extension of the support plate 42a, the relatively weak coupling cooking surface section 20a is arranged in an area of the corresponding cooking surface partial area 16a, 18a which is opposite to the other of the partial cooking surface areas 16a, 18a in the transverse direction 46a. When viewed perpendicularly on the main extension plane of the support plate 42a, the relatively moderate coupling cooking surface section 22a is arranged in an area of the corresponding partial cooking surface area 16a, 18a that is arranged in the transverse direction 46a between the cooking surface section 24a of relatively intense coupling and the cooking surface section 20a of relatively weak coupling.
[0118]
[0119] In the operating state, the control unit 38a divides the cooking surface sections 20a, 22a, 24a from the corresponding cooking surface area 16a, 18a depending on their position and / or distance with respect to another of the areas partial cooking surface 16a, 18a. In the operating state, the control unit 38a divides the cooking surface sections 20a, 22a, 24a from the corresponding cooking surface area 16a, 18a depending on the coupling of the heating units 12a defining the surface section of cooking 20a, 22a, 24a with heating units 12a that partially define another of the partial cooking surface areas 16a, 18a.
[0120]
[0121] In the operating state, the control unit 38a selects for one of the cooking surface sections 20a, 22a, 24a a detection mode of the set of detection modes depending on the overlapping of an area near 26a to a heating zone 28a of the heating zone configuration and the cooking surface section 20a, 22a, 24a. By means of Figures 2 to 13, several examples are described below for the selection of the set of detection modes as a function of the overlapping of an area near 26a to a heating zone 28a of the heating zone configuration and one of the cooking surface sections 20a, 22a, 24a. However, several detection modes that are contained in the set of detection modes are first exposed.
[0122]
[0123] The set of detection modes has a detection mode which is referred to below as the "relatively intense coupling detection mode." In the operating state, the control unit 38a selects the "relatively intense coupling detection mode" of the assembly of detection modes in the case of a detection area 30a that overlaps the coupling cooking surface section 24a relatively intense of the cooking surface sections 20a, 22a, 24a and which is arranged in a near area 26a to a heating zone 28a of the heating zone configuration. In the case that the "relatively intense coupling detection mode" is selected, the control unit 38a deactivates in the operating state the heating units 12a that heat the heating zone 28a in order for the detection to be carried out .
[0124]
[0125] The set of detection modes has a detection mode which is referred to below as the "relatively moderate coupling detection mode." In the operating state, the control unit 38a selects the "relatively moderate coupling detection mode" of the assembly of detection modes in the case of a detection area 30a that overlaps the cooking surface section 22a of relatively moderate engagement of the cooking surface sections 20a, 22a, 24a and which is arranged in a nearby area 26a to a heating zone 28a of the heating zone configuration. In the case that the "relatively moderate coupling detection mode" is selected, the control unit 38a deactivates in the operating state the heating units 12a that heat the heating zone 28a in order for the detection to be carried out .
[0126]
[0127] The set of detection modes has a detection mode which is referred to below as "detection mode within the partial cooking surface areas." In the operating state, the control unit 38a selects the "detection mode within the partial cooking surface areas ”of the set of detection modes in the case of a detection area 30a that overlaps the cooking surface section 20a, 22a of relatively weak coupling or relatively moderate coupling of the surface sections of cooking 20a, 22a, 24a. In the "detection mode within the partial cooking surface areas", a detection carried out in the operating state by at least one heating unit 12a that partially defines one of the partial cooking surface areas 16a, 18a is synchronized with at least one other first heating unit 12a that partially defines the same of the partial cooking surface areas 16a, 18a if the heating zone 28a is partially arranged in the first partial cooking surface area 16a and in the second partial area of cooking surface 18a.
[0128]
[0129] The set of detection modes has a detection mode which is referred to below as "detection mode between the partial cooking surface areas." In the operating state, the control unit 38a selects the "detection mode between the partial cooking surface areas ”of the set of detection modes in the case of a detection area 30a that is arranged in the second partial cooking surface area 18a if the second partial cooking surface area 18a has no areas of heating 28a of the heating zone configuration. In the "detection mode between the partial cooking surface areas", a detection carried out by second heating units 12a2 is synchronized with first heating units 12a1 of the first heating units 12a1 if the second partial cooking surface area 18a does not have heating zones 28a of the heating zone configuration.
[0130]
[0131] In the operating state, the control unit 38a selects the "detection mode between the partial cooking surface areas" of the set of detection modes in the case of a detection area 30a which is arranged in the first partial area of cooking surface 16a if the first partial cooking surface area 16a does not have heating zones 28a of the heating zone configuration. In the "detection mode between partial cooking surface areas", a detection carried out by first units heating 12a1 is synchronized with second heating units 12a2 of the second heating units 12a2 if the first partial cooking surface area 16a does not have heating zones 28a of the heating zone configuration.
[0132]
[0133] At least in the case of the "relatively intense coupling detection mode" and the "relatively moderate coupling detection mode", the control unit 38a takes into account in the operating state when the detection is carried out the degree to which the heating units 12a are covered by the cooking battery 60a resting on it. In the operating state, the control unit 38a detects a new firing battery 60a supported on the variable cooking surface area 14a, in particular, on the cooking surface section 24a of relatively intense engagement and / or in the section of relatively moderate coupling cooking surface 22a, which is supported on at least two heating units 12a arranged adjacent to each other whose central points are arranged on a straight line 32a that is oriented perpendicularly to a field edge of cooking 34a, only if at least one of the corresponding heating units 12a is covered at least 70%. In the operating state, the control unit 38a detects a new firing battery 60a supported on the variable cooking surface area 14a, in particular, on the cooking surface section 24a of relatively intense engagement and / or in the section cooking surface 22a coupling relatively moderate, which is supported on at least two heating units 12a disposed adjacent to each other whose central points are arranged on a straight line 36a that is obliquely oriented with respect to at least one cooking field edge 34a, only in the if at least one of the corresponding heating units 12a is covered at least 30%.
[0134]
[0135] In a procedure for the start-up of the cooking field device 10a, for the detection of a new cooking battery 60a supported on the variable cooking surface area 14a, in the operating state at least one detection mode is selected of the set of possible detection modes depending on an existing heating zone configuration in the variable cooking surface area 14a. Next, the execution of the process is described by means of various heating zone configurations selected by way of example (see Figures 2 to 13). Next, the cooking battery 60a which is heated by a heating zone 28a of the heating zone configuration is indicated by a cross-hatch. The new firing battery 60a supported on the variable cooking surface area 14a that is detectable by the control unit 38a in the operating state is indicated by a horizontal parallel scratch. The new firing battery 60a supported on the variable cooking surface area 14a in which the control unit 38a dispenses with its detection in the operating state is indicated by a parallel vertical scratch.
[0136]
[0137] Figure 2 shows a cooking battery 60a heated by a heating zone 28a of the heating zone configuration. The cooking battery 60a already supported and heated covers only first heating units 12a1, which define the first partial cooking surface area 16a. The second partial cooking surface area 18a does not have heating zones 28a of the heating zone configuration. In the operating state, the control unit 38a selects for a detection area 30a which is arranged in the second partial cooking surface area 18a the detection mode called "detection mode between the partial cooking surface areas" of the set of detection modes.
[0138]
[0139] Figure 3 shows a cooking battery 60a heated by a heating zone 28a of the heating zone configuration. The cooking battery 60a already supported and heated largely covers the heating units 12a of the relatively intense coupling cooking surface section 24a and the relatively moderate coupling cooking surface section 22a of the first partial area of cooking surface 16a. The cooking battery 60a already supported and heated largely covers the heating units 12a of the relatively intense coupling cooking surface section 24a and the relatively moderate coupling cooking surface section 22a of the second partial surface area of cooking 18a. In the operating state, the control unit 38a selects the detection mode called "detection mode within the partial cooking surface areas" for a detection area 30a which is arranged in the first partial cooking surface area 16a in particular, in the cooking surface section 20a of relatively weak coupling of the first partial cooking surface area 16a and, in particular, in an area close to the heating zone 28a. In the operating state, the control unit 38a selects the detection mode called "detection mode within the partial cooking surface areas" for a detection area 30a which is arranged in the second partial cooking surface area 18a, specifically, in the section of cooking surface 20a of relatively weak coupling of the second partial area of cooking surface 18a and, in particular, in a nearby area 26a to the heating zone 28a.
[0140]
[0141] Figure 4 shows a cooking battery 60a heated by a heating zone 28a of the heating zone configuration. The cooking battery 60a already supported and heated largely covers one of the heating units 12a of the cooking surface section 24a of relatively intense engagement of the first partial cooking surface area 16a. The detection area 30a is arranged in an area close to the heating zone 28a and overlaps the cooking surface section 24a of relatively intense engagement of the second partial cooking surface area 18a. The second partial cooking surface area 18a does not have heating zones 28a of the existing heating zone configuration. In the operating state, the control unit 38a selects from the set of detection modes the detection mode called "detection mode between the partial cooking surface areas".
[0142]
[0143] Figure 5 shows a heating zone 28a of the heating zone configuration, which heats a firing battery 60a, which extends in the transverse direction 46a for much of the first partial cooking surface area 16a and which it is also partially arranged in the second partial cooking surface area 18a. In the example shown, the heating zone 28a overlaps the three cooking surface sections 20a, 22a, 24a of the first partial cooking surface area 16a and the coupling cooking surface section 24a relatively intense of the second partial cooking surface area 18a. Alternatively, the heating zone 28a could additionally overlap with the relatively moderate coupling cooking surface section 22a of the second partial cooking surface area 18a, which is shown in FIG. 5 in a broken line. A detection area 30a disposed in an area near 26a to the heating zone 28a overlaps the relatively intense coupling cooking surface section 24a of the second partial cooking surface area 18a. In the operating state, the control unit 38a selects the detection mode called "relatively intense coupling detection mode." In the example shown, the control unit 38a prevents the detection of the new cooking battery 60a supported by the detection area 30a, since this firing battery 60a is supported on two second heating units 12a2 arranged adjacent to each other whose central points are arranged on a straight line 32a that is oriented perpendicularly with respect to a field edge of cooking 34a, and only each of the second heating units 12a2 is covered in less than 70%.
[0144]
[0145] Figure 6 shows a heating zone 28a of the heating zone configuration, which heats a cooking battery 60a, which is formed by a part of the first heating units 12a1 of the cooking surface section 24a of relatively engaging coupling intensity of the first partial cooking surface area 16a and by a part of the second heating units 12a2 of the relatively intense coupling cooking surface section 24a of the second partial cooking surface area 18a. A detection area 30a is disposed in an area near 26a to the heating zone 28a and overlaps the cooking surface section 24a of relatively intense engagement of the first partial cooking surface area 16a. In the operating state, the control unit 38a selects for the detection area 30a the detection mode called "detection mode within the partial cooking surface areas". The detection area 30a is arranged in a nearby area 26a to the heating zone 28a and overlaps with the cooking surface section 24a of relatively intense engagement of the second partial cooking surface area 18.a In the operating state, the control unit 38a selects for the detection area 30a the detection mode called "detection mode within the partial cooking surface areas".
[0146]
[0147] Figure 7 shows a heating zone 28a of the heating zone configuration, which heats a cooking battery 60a, which is formed by a part of the first heating units 12a1 of the cooking surface section 24a of relatively intense coupling of the first partial cooking surface area 16a and by a part of the second heating units 12a2 of the cooking surface section 24a of relatively intense coupling of the second partial cooking surface area 18a. A detection area 30a is disposed in an area near 26a to the heating zone 28a and overlaps the cooking surface section 24a of relatively intense engagement of the first partial cooking surface area 16a and the surface section of cooking 24a of relatively intense coupling of the second partial cooking surface area 18a. In the operating state, the control unit 38a selects for the detection area 30a the detection mode called "relatively strong coupling detection mode." A new cooking battery 60a supported is placed on four heating units 12a arranged in adjacent to each other Each of the heating units 12a on which the cooking battery 60a rests has central points that are arranged on a straight line 32a that is oriented perpendicularly with respect to the cooking field edge 34a. two of the heating units 12a on which the cooking battery 60a is supported have central points that are arranged on a straight line 36a that is oriented obliquely with respect to the cooking field edge 34a. The new cooking battery 60a supported has a coverage of less than 30% in each of the heating units 12a on the which is supported, however, the control unit 38a detects in the operating state the new cooking battery 60a supported, since two of the heating units 12a on which the cooking battery 60a is placed are arranged outside the area next 26a to the heating zone 28a.
[0148]
[0149] Figure 8 shows a heating zone configuration with three heating zones 28a1, 28a2, 28a3. The first heating zone 28a1 of the heating zones 28a is partially arranged in the relatively intense coupling cooking surface section 24a and partially in the relatively moderate coupling cooking surface section 22a of the first partial cooking surface area 16th The second heating zone 28a2 of the heating zones 28a is partially arranged in the relatively intense coupling cooking surface section 24a and partially in the relatively moderate coupling cooking surface section 22a of the first partial cooking surface area 16th The third heating zone 28a3 of the heating zones 28a is arranged in the relatively weak coupling cooking surface section 20a of the second partial cooking surface area 18a. A detection area 30a is arranged in an area near 26a to the heating zones 28a and overlaps with the cooking surface section 24a of relatively intense engagement and partially with the cooking surface section 22a of relatively moderate engagement of the second partial cooking surface area 18. In the operating state, the control unit 38a selects for the detection area 30a the detection mode called "relatively strong coupling detection mode." A first new cooking battery 60a1 supported in the detection area 30a is supported by an area near 26a to the first heating zone 28a1 on heating units 12a2 arranged adjacent to each other whose central points are arranged on a straight line 36a that is oriented obliquely with respect to the cooking field edge 34a. cooking 60a1 supported has at least one of the heating units 12a2 covering at least 30% The control unit 38a detects in the operating state the first new cooking battery 60a1 supported A second new cooking battery 60a2 supported in the detection area 30a is supported in an area near 26a to the second heating zone 28 a2 on heating units 12a2 arranged adjacent to each other whose central points are arranged on a straight line 32a that is oriented perpendicularly with respect to the cooking field edge 34a. The second new firing battery 60a2 supported has a coverage of less than 70% with each of the heating units 12a2. In the operating state, the control unit 38a prevents the detection of the second new cooking battery 60a2 supported.
[0150]
[0151] Figure 9 shows a heating zone configuration with two heating zones 28a1, 28a2. The first heating zone 28a1 of the heating zones 28a is arranged in the cooking surface section 24a of relatively intense engagement of the first partial cooking surface area 16a. The second heating zone 28a2 of the heating zones 28a is arranged in the relatively weak coupling cooking surface section 20a of the second partial cooking surface area 18a. A detection area 30a is disposed in an area near 26a to the first heating zone 28a1 and overlaps with the cooking surface section 24a of relatively intense engagement of the second partial cooking surface area 18a. In the operating state, the control unit 38a selects for the detection area 30a the detection mode called "relatively strong coupling detection mode." A new cooking battery 60a supported in the detection area 30a is supported by a area near 26a to the first heating zone 28a1 on heating units 12a2 arranged so adjacent to each other whose central points are arranged on a straight line 36a that is oriented perpendicularly with respect to the cooking field edge 34a. The new cooking battery 60a supported has a coverage of less than 70% with each of the heating units 12a2. In the operating state, the control unit 38a prevents the detection of the second new cooking battery 60a2 supported.
[0152]
[0153] Figure 10 shows a heating zone configuration with two heating zones 28a1, 28a2. The first heating zone 28a1 of the heating zones 28a is partially arranged in the relatively intense coupling cooking surface section 24a and partially in the relatively moderate coupling cooking surface section 22a of the first partial cooking surface area 16th The second heating zone 28a2 of the heating zones 28a is arranged in the relatively weak coupling cooking surface section 20a of the second partial cooking surface area 18a. A detection area 30a is disposed in an area near 26a to the first heating zone 28a1 and overlaps with the cooking surface section 24a of relatively intense engagement of the second partial cooking surface area 18a. A new firing battery 60a resting on the detection area 30a is resting on heating units 12a2 arranged adjacent to each other whose central points are arranged on a straight line 32a that is oriented perpendicularly with respect to the cooking field edge 34a . The new cooking battery 60a supported has a coverage of less than 70% with each of the heating units 12a2. In the operating state, the control unit 38a prevents the detection of the new cooking battery 60a supported.
[0154]
[0155] Figure 11 shows a heating zone configuration with two heating zones 28a1, 28a2. The first heating zone 28a1 of the heating zones 28a is partially arranged in the relatively intense coupling cooking surface section 24a, partially in the relatively moderate coupling cooking surface section 22a, and partly in the surface area of relatively weak coupling cooking 20a of the first partial cooking surface area 16a. The second heating zone 28a2 of the heating zones 28a is arranged in the relatively weak coupling cooking surface section 20a of the second partial cooking surface area 18a. A detection area 30a is arranged in an area near 26a to the first heating zone 28a1 and overlaps the cooking surface section 24a of relatively intense engagement and with the cooking surface section 22a of relatively moderate engagement of the second partial cooking surface area 18a. A new cooking battery 60a supported partially overlaps with the detection area 30a and partially with the cooking surface section 20a of relatively weak engagement of the second partial cooking surface area 18a.

[0157] Figure 12 shows a heating zone configuration with two heating zones 28a1, 28a2. The first heating zone 28a1 of the heating zones 28a is partially arranged in the relatively intense coupling cooking surface section 24a and partially in the relatively moderate coupling cooking surface section 22a of the first partial cooking surface area 16th The second heating zone 28a2 of the heating zones 28a is partially arranged in the relatively intense coupling cooking surface section 24a and partially in the relatively moderate coupling cooking surface section 22a of the second partial cooking surface area 18. A detection area 30a1 is arranged in an area near 26a to the first heating zone 28a1 and overlaps with the cooking surface section 24a of relatively intense engagement of the second partial cooking surface area 18a. A new cooking battery 60a2 supported in the detection area 30a1 has a coverage of more than 70% with one of the heating units 12a. In the operating state, the control unit 38a selects the detection mode called "relatively strong coupling detection mode."

[0159] Figure 13 shows a heating zone configuration with a heating zone 28a, which is partially arranged in the surface section of relatively intense coupling cooking 24a of the first partial cooking surface area 16a and partially in the cooking surface section 24a of relatively intense coupling of the second partial cooking surface area 18a. A detection area 30a1 is disposed in an area near 26a to the heating zone 28a and overlaps the relatively moderate coupling cooking surface section 22a of the first partial cooking surface area 16a. In the operating state, the control unit 38a selects the detection mode called "detection mode within the partial cooking surface areas." A detection area 30a2 is arranged in an area near 26a to the heating zone 28a and overlaps with the relatively moderate coupling cooking surface section 22a of the second partial cooking surface area 18. A new cooking battery 60a2 supported partially overlaps with the detection area 30a2 and partially with the cooking surface section Relatively weak coupling 20a of the second partial cooking surface area 18.a In the operating state, the control unit 38a selects the detection mode called "detection mode within the partial cooking surface areas".
[0160]
[0161] Next, another example is described by means of Figures 14 and 15. First, a new firing battery 60a1 is supported on a detection area 30a, which overlaps the cooking surface section 24a relatively engaging intense of the first partial cooking surface area 16a and with the cooking surface section 24a of relatively intense engagement of the second partial cooking surface area 18a. The new cooking battery 60a1 supported is placed on heating units 12a2 arranged adjacent to each other whose central points are arranged on a straight line 32a that is oriented perpendicularly with respect to the cooking field edge 34a. In the operating state, the control unit 38a detects the new firing battery 60a1 supported by the absence of heated heating zone 28a of a heating zone configuration. The control unit 38a emits the position of the new firing battery 60a1 supported through the user interface 44a. In the first place, heating of the new cooking battery 60a1 supported is prevented when a control input is not made through the user interface 44a. Next, two other firing batteries 60a are supported and heated, resulting in two heating zones 28a1, 28a2 of a heating zone configuration (see Figure 15). The first heating zone 28a1 of the heating zones 28a is partially arranged in the cooking surface section 24a of relatively intense engagement, partially in the cooking surface section 22a of relatively moderate coupling, and partially in the cooking surface section 20a of relatively weak coupling of the first partial area of cooking surface 16a. The second heating zone 28a2 of the heating zones 28a is arranged in the relatively weak coupling cooking surface section 20a of the second partial cooking surface area 18a. Then, the cooking battery 60a1 detected above is removed, which is shown in Figure 15 in a broken line. As a consequence of the heating zones 28a1, 28a2 now existing and the lack of coverage of the heating units 12a2 by the cooking battery 60a1, the control unit prevents the detection of the withdrawal of the cooking battery 60a1 in favor of the avoidance of intermodulation hums.
